Question about [ERROR] No such install plugin for obproxy-3.2.0

[bo-er]

I'm installing Oceanbase on centOS 7

Linux ob1 3.10.0-862.14.4.el7.x86_64 #1 SMP Wed Sep 26 15:12:11 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I get this error and the error message is kind of confusing:

[root@ob1 ~]# obd cluster autodeploy ob-test -c ob-deploy.yml  -A
oceanbase-ce-3.1.4 already installed.
Package obproxy-3.2.0 is available.
obagent-1.1.2 already installed.
[ERROR] No such install plugin for obproxy-3.2.0

What does this message mean? Install is a verb, not a noun. I think this should be replaced with [ERROR] No such plugin for installing obproxy-3.2.0. Correct me if I'm wrong.
